Description
본 발명은 진공청소기에 관한 것으로서, 보다 상세하게는 냉각팬에 의해 흡입한 외부 공기를 이용하여 임펠러 구동모터를 냉각시키도록 된 배기환류 청소기에 관한 것이다.The present invention relates to a vacuum cleaner, and more particularly, to an exhaust reflux cleaner configured to cool an impeller drive motor using external air sucked by a cooling fan.
일반적으로, 진공청소기는 청소하고자 하는 부위의 공기를 흡입하여 집진포대와 배기필터를 통과하도록 배기시킴으로써, 흡입 공기중의 분진이나 이물들을 포집하게 된다. 따라서, 이러한 진공청소기는 사용시 악취 등이 내포된 배기 공기의 확산으로 인하여 사용자에게 불쾌감을 유발시키는 문제점을 안고 있다. 이와 같은 기존의 진공청소기가 안고 있는 문제점을 개선하기 위해 개발된 것이 소위, 배기환류형 진공청소기로서, 이는 흡입 공기를 브러쉬측으로 배기시켜 재흡입하도록 하여 순환시킴에 따라 원천적으로 불쾌감을 유발하는 배기 공기의 유출을 막을 수 있도록 되어 있다.In general, the vacuum cleaner sucks the air in the area to be cleaned and exhausts it through the dust collecting bag and the exhaust filter, thereby collecting dust or foreign matter in the intake air. Therefore, such a vacuum cleaner has a problem of causing discomfort to the user due to the diffusion of the exhaust air containing the odor when using. The so-called exhaust reflux vacuum cleaner was developed to improve the problems of the existing vacuum cleaner, which exhausts the intake air to the brush side and re-suctions it to circulate to cause unpleasant exhaust air. It is designed to prevent spills.
도 1은 종래의 배기환류형 진공청소기의 일예를 보인 것으로서, 흡입통로(11)와 배출통로(12)를 가진 본체(10)와, 상기 흡입통로(11)상에 설치되는 집진실(13) 및 모터(15)에 의해 회전구동하는 임펠러(14)와, 상기 본체(10)와 연결되며 상기 흡입통로(11)와 배출통로(12)에 각각 연통되도록 구획된 흡입관로(21)와 배기관로(22)를 구비한 연결관(20)과, 상기 연결관(20)의 단부에 설치되는 브러쉬(23)를 포함하여 구성된다.1 shows an example of a conventional exhaust reflux vacuum cleaner, a main body 10 having a suction passage 11 and a discharge passage 12, a dust collecting chamber 13 installed on the suction passage 11, and An impeller 14 driven to rotate by a motor 15 and a suction pipe passage 21 and an exhaust pipe passage which are connected to the main body 10 and are respectively communicated with the suction passage 11 and the discharge passage 12. It comprises a connecting pipe (20) having a 22, and a brush (23) provided at the end of the connecting pipe (20).
상기와 같은 구성을 가지는 종래의 배기환류 청소기에 따르면, 상기 모터(15) 및 임펠러(14)의 회전에 의해 상기 브러쉬(23)가 청소하고자 하는 부위의 공기를 높은 흡인력으로 흡입하게 된다. 이와 같이 흡입된 공기는 상기 연결관(20)의 흡입관로(21)를 통해 집진포대(13)를 통과하게 되는데, 이때 흡입 공기중에 포함되어 있는 분진이나 이물들이 집진포대(13)에 흡착 포집된다.According to the conventional exhaust reflux cleaner having the configuration as described above, by the rotation of the motor 15 and the impeller 14 to suck the air of the area to be cleaned by the brush 23 with a high suction force. The air sucked in this way passes through the dust collecting bag 13 through the suction pipe passage 21 of the connecting pipe 20, wherein dust or foreign matter contained in the suction air is collected by the dust collecting bag 13. .
상기와 같이 집진포대(13)에 의해 분진이나 이물들이 걸러진 흡입 공기는 상기 배출통로(12)와 배기관로(22)를 거쳐 상기 브러쉬(23)로 배기되도록 분사된다. 이때 분사된 배기 공기는 상기 브러쉬(23)와 근접된 바닥면의 분진이나 이물들을 편승시켜서 상기 브러쉬(23)를 통해 재흡입된다.As described above, the intake air in which dust or foreign matter is filtered out by the dust collecting bag 13 is injected to be exhausted to the brush 23 through the discharge passage 12 and the exhaust pipe passage 22. At this time, the injected exhaust air is sucked back through the brush 23 by piggybacking dust or foreign matter on the bottom surface adjacent to the brush 23.
그런데, 상술한 바와 같은 종래의 배기환류 청소기는, 상기 브러쉬(23)로 흡입된 공기가 순환하면서 모터(15)를 냉각시키게 되는데, 이때 모터(15)의 구동발열에 노출되어 온도가 상승된 환류 공기가 재흡입됨에 따라 냉각효율이 지속적으로 저하된다. 따라서, 청소기의 가동이 지속됨에 따라 모터(15)가 과열되어 성능 저하를 초래하게 되므로, 브러쉬에 의한 공기 흡입력이 저하되어 청소기의 성능과 효율을 떨어뜨리는 문제점이 있다.By the way, the conventional exhaust reflux cleaner as described above is to cool the motor 15 while the air sucked by the brush 23 is circulated, at this time exposed to the driving heat of the motor 15 to increase the temperature of the reflux As the air is reabsorbed, the cooling efficiency continues to decrease. Therefore, as the operation of the cleaner continues, the motor 15 is overheated, resulting in deterioration of performance. Thus, the air suction force by the brush is lowered, thereby degrading the performance and efficiency of the cleaner.

It is to provide an exhaust reflux cleaner that improves the cleaning performance and efficiency by preventing overheating.
